Exercise motion analysis system, exercise motion analysis method, and exercise motion analysis program

Abstract

In an exercise motion analysis system, an input unit inputs motion data corresponding to multiple types of motion parameters indicating motion states of a user who is running, and index data corresponding to an index parameter indicating exercise performance of the user in the running. An estimation unit estimates which of multiple types of motion parameters has a higher degree of contribution to enhancement of exercise performance for the user. An item storage unit stores information on multiple types of wearing tools. Based on wearing tool property data that includes a property, determined for each of multiple types of wearing tools, indicating which of multiple types of motion parameters is changed to contribute to enhancement of exercise performance, a selection unit selects a wearing tool having a property of changing a motion parameter of a type estimated by the estimation unit and thereby contributing to enhancement of exercise performance.
